The NYS Septic System Replacement Fund, explained in plain English

New York will reimburse eligible homeowners for a large share of the cost of replacing a failing septic system or cesspool. Here's who qualifies, how much you can get, and the mistakes that disqualify people.

How much money is available

Under the program rules updated in 2025, eligible property owners can be reimbursed:

• 50% of eligible costs, up to $10,000, for installing a conventional replacement system; or
• 75% of eligible costs, up to $25,000, for installing an enhanced septic system — one with advanced treatment that removes nitrogen or phosphorus.

The state deliberately made the enhanced-system reimbursement richer, so that a better system can end up costing you the same as — or less than — a conventional one. In 2025 the Governor's office announced a further $30 million for Round 5 of the fund, so the program is active and funded, but counties award money while their allocations last.

Who qualifies

Three conditions have to line up:

1. Your county participates. The fund is administered county by county. Putnam, Dutchess, Rockland, Westchester and many others participate; each has a local program contact, usually in the health department.
2. Your property is in a priority area. In general that means within about 250 feet of a specific "priority waterbody" — a lake, reservoir, or stream the DEC has designated as impaired or as drinking-water supply. Each county's list is different, and it changes between funding rounds. Systems slightly beyond 250 feet can sometimes still qualify if they're failing and affecting the waterbody.
3. Your system is failing or likely to fail. Backups, surfacing sewage, a deteriorated or cracked tank, a saturated leach field, or a cesspool (which the program specifically wants to eliminate) all count. Counties typically verify with an inspection or dye test.

The process, step by step

1. Call your county's program contact (health department in most counties) and ask two questions: is my property within a priority area, and is funding currently available?
2. Document the failure. The county will typically want an inspection report, a dye test, or their own site visit confirming the system is failing or likely to fail.
3. Submit the application and wait for the award letter. Do not sign anything with a contractor yet.
4. Get quotes from licensed installers. In Putnam County, for instance, septic work must be done by a county-registered contractor — using an unregistered one can void both your permit and your reimbursement. (Our Putnam installer list is here.)
5. Build, keep every receipt, and submit for reimbursement. The grant is a reimbursement — you (or your financing) pay the contractor, then the county pays you back the covered share. Some costs don't count: routine pumping, permit fees, sales tax, and landscaping beautification are typical exclusions.

Other programs that stack or substitute

The state fund is the headline program, but it's not the only money available in this region:

• NYC DEP East of Hudson Septic Rehabilitation Program — if you live in the New York City watershed in Putnam or Westchester (the Kensico, Boyd Corners, West Branch, Cross River, Croton Falls, East Branch, Diverting, Middle Branch, or Bog Brook reservoir basins), a separate reimbursement program funded by NYC covers repair or replacement of failing systems. Many homeowners near the reservoirs qualify for this even when they don't qualify for the state fund.
• County income-based assistance — for example, the Putnam County Housing Corporation offers income-qualified grants and loans that can cover septic repairs, with a separate program for homeowners over 60 that can even cover inspection and pumping.
• USDA Section 504 Home Repair loans and grants — for low-income rural homeowners; grants of up to $10,000 for those 62+ who can't repay a loan.
